To 00% whom it may concern:

Be it known that I, WILLIAM BENNETT, a citizen of the UnitedStates,residingatBrockport, in the county of Elk and State ofPennsylvania, have invented certain new and useful Improvements inStump-Pullers; andIdo hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for extracting stu mps, looseningboulders, and moving heavy objects requiring the expenditure ofconsiderable force to start and lift them. The device is most especiallydesigned for field use to clear the same of stumps of trees, roots,stones, and boulders.

The purpose of the invention is to provide a structure capable of easytransportation and movable from one stump, boulder, or objeet to anotherand which will be durable, convenient of operation, and effective in itsworkings.

The invention consists, essentially, of a stand or foldable structure tosit over the object to be moved, a floating lever, and a block andtackle connecting the long arm of the lever with the frame.

For a full description of the invention and the merits thereof,and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference is to be had to the followingdescription and the drawings hereto attached.

While the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of the apparatus as it appears when inoperation. Fig. 2 is a front View. Fig. 3 is a side elevation. Fig. 4 isa detail View of the means for connecting the bars of the frame andforming a fulcrum for the lever. Fig. 5 is a sectional detail showingthe manner of connecting the lower end of a bar to the'base-timber.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The framework structure or stand of the device is portable and of afolding character and comprises three bars 1, 2, and 8, which areconnected at their upper ends in any substantial manner and diverge attheir lower ends. One of the bars, as 1, is provided at its lower endwith a base-timber 4, and the other bars 2 and 3 are connected attheirlower ends by a base-timber 5 common to-each. The base-timbers 4and 5 prevent the lower ends of the several bars entering the ground toa great depth when the apparatus is in operation. While the upper endsof the bars comprising the structure may be connected in any desired andsubstantial way, it is preferred to unite them by means whichhereinafter will be more particularly referred to in connection with thesupport for the floating lever 6. The lower ends of the bars are reducedand passed through openings formed in thebase-timbers, their projectingends be ing pointed, as shown at 7, to enter the ground to a sufficientdepth to prevent slipping of the base-timbers when the apparatus is setup for operation. Shoulders 8 are formed at the bases of the reducedends of the bars and overlap the base-timbers and limit the downwardmovement of the bars with reference thereto.

The floating lever 6 has a fulcrum-support at one end suspended from thestructure, and its opposite end is adapted to be connected by block andtackle with the upper end of the structure, preferably to the upperportion of the bar 1, which is projected above the pivot-fastening asuliicient distance for this rope or cable 11 is made fast to apulley-block, as 9, and the opposite end portion passes un-' der adirecting-pulley 12, applied to the basetimber 5 at about anintermediate point, the

drive or team being hitched to the outer end of the rope to apply powerthereto when extracting a stump or loosening a boulder.

Companion rods 13 connect the pivotal end of the leverwith the upper endof theframe, and each is provided at its respective ends with an eye 14and a bent terminal portion 15. The bent end 15 of one of the rods 13passes through openings formed in coincident relation in the upper endsof the bars 1, 2, and 3 and pivotally connects them, and the projectingportion of the bent end receives the eye 14 of the other rod. The latterrod has its bent end passed through an opening in the inner end of thelever 6 and constitutes a fulcrum therefor, its projecting end receivingan eye of the first-mentioned rod. It will thus be seen that the tworods 13 are oppositely disposed-that is, the bent end of one isuppermost and the bent end of the other lowermost, the eye ends of therods being similarly disposed, so as to receive the projecting endportions of the bent terminals. Cotter pins or keys 16 are applied tothe projecting end portions 15 to retain the eyes ll in engagementtherewith after the parts have been properlyassembled.Therods13aredisposed upon opposite sides of the lever and upperconnected ends of the bars. Hence the strain is equalized upon the frameand lever and torsional strain is obviated.

A draft-chain 17 has connection at its upper end with the lever 6 and isprovided at its lower end with means for engagement with the stump,root, boulder, or other object to be moved or lifted, said draft-chainbeing applied to the lever at a point between its fulcrum and point ofapplication of power.

The apparatus is capable of being quickly dismembered, so as to bepacked or stored in a small compass either for transportation orstorage, and can be quickly set up when required for use. When it isrequired to extract a stump or loosen a boulder, the structure is placedover the object to be moved about, as illustrated in Fig. 1, and thelower end of the draft-rope 17 is hitched or otherwise connected to theobject to be loosened. The outer end of the rope or cable 11 is hitchedto the team, and when all is in readiness the draft is applied by urgingthe team forward, when the outer end of the lever 6 will be elevated andimpart an upward pull upon'the' draft-rope 17 and stump or object towhich said draft-rope is hitched and effect a loosening or liftingthereof. It will be observed that the lever 6 is free to move, therebyequalizing the strain upon its opposite end por tions, which is ofmaterial advantage. 4

Having thus described the invention, what is claimed as new is 1. Inelevating apparatus of the character specified, a frame composed of aseries of bars, a lever, companion rods having their opposite endsprovided with respectively bent portions and eyes and oppositelydisposed with their bent ends engaging with the said lever and bars andhaving the projecting portions of the bent ends receiving thecorresponding eyes at the other end of the rod, substantially as setforth.

2. The herein-described apparatus consisting of upwardly-inclined barshaving their lower ends reduced and formed with shoulders and pointedterminals, base-timbers ap* plied to the lower ends of the bars with thepointed extremities of the lever projecting to penetrate the surface ofthe ground, a floating lever, companion rods having their ends providedwith respectively eyes and bent terminal portions, said rods beinginversely disposed and having their bent terminal portions engagingwith, respectively, the lever and converging ends of the frame-bars andserving as connecting means for the latter, the eye of one rod beingengaged with the projecting portion of the bent terminal of the otherrod and held thereon from accidental displacement, a block and tackleconnecting the free end of the lever with the upper end of one of theframe-bars and adapted to have the power applied thereto, adirection-pulley applied to one of the base-timbers for the rope of theblock and tackle, and a draft-rope applied to the floating lever andadapted to be connected with the stump or object to be moved,substantially as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

VILLIAM BENNETT.
